INTERN-AL-COMBUSTION BOILER.

Application led August-30, 1918. Serial No. 252,067.

To all whom vit may concern Be it known that I, ALEXANDER SnioLnR,

Y a residentof Chicago, Illinois, have invented a certain new and useful Improvement in Internal-Combustion Boilers, of Whichv the following is 'a specification.

This invention relates to the burning of hydro-carbon to produce a flame of hi h temperature, and more particularly to t e generationl of steam by means of a burner of this kind, or` ofjany suitable character.

Generally stated, the object of the invention is ltov provide aiiovel and improved apparatus for' converting hydro-carbon into bo ler, whereby pressure' in the boiler is pro- 'dimette-billy by the, generatie of steam,

but 'also bi the accumulation pf are products fief-a prfsiidefertain ,def tails and certain" features Aof construction l general'eliiciency and the'des'irability ofan V apparatus of this particular character.

To theseand other-useful ends the invention consists in mattershereinafter set forth and claimed. I

In the accompanying drawings- Fig. 1 's a longitudinal section 'ofan internal combustion boiler and oil burning apparatus embodying the principles of the invention.

Fig. 2 yis an enlarged cross section online 2 2 in Fig. 1.

Fig. 3 is' an enlarged detail sectional view of the burner, showing the automatic valve which forms a part thereof.

As thus. illustrated, the invention comprises a boiler 1`of anyY suitable character, provided at one end with an opening 2 which is closed bythe flanged union 3, the latter being rigid with the body 4 which cncloses the burner. This body 4 is closed at its outer end by a removable plate 5, and

A has its inner end'provided with a wall 6 having a tapered extension 7 which ter- `,rod 19 that extends downward Into th valve Y 'valve to' prevent the back pressure of the' Aininates in the enlargement which contains the explosion chamber 9 of the burner apparatus. This enlargement 9 has a ilaring extension 10 by which to direct the flame into the water-within the boiler.

A nozzle 11 is inserted through the plate o, and into the funnel-like opening 12 formed in the partition plate 13, and this4 opening 12 terminates in a valve chamber Y 14, and the latter terminates in a tpered lnozzle 15 that extends into the' tapered extension 7 previously described, whereb this nozzle' 15 extends nearly to the exp osion chamber 9, but with space between the outer surface 'of said nozzle' and the inner sul-face ot' theextension 7, in order that heated air may be mixed with the jetof'gas which ably accomplished by 'means of a pipe t llf3 which leads to the chamber 17 in the' burner head or body 4, it being observed that this.,

chamber 17 communicates with the Vspace around' the nozzle 15, sothat theairsliter.-

Vescapes from' said. nozzle. This is prefer@- Aing Said Chamber 17 will esape'iitcthe explosion chamber 9 where it will with tha-aas and Cause an explesiof, -'-.Th pipe ihas a valve 18 which isvoperetd by a r chamber 14 (seeliig. 3), thischaiiiben ing'a pivoted valve20 which acts' as a ch explosions in the chamber 9 lfrom 'extend-V ing backward into the mixing chamber 21 inthe burner body. A s ring 22 holds the rod 19 normally in 'a yepressed will raise the rod 19 and thereby openthe valve 18 and cause heated air to enterthe chamber 17, as previously described. lThe valve mechanism, comprising a hollow head or casing 23, is arranged to support the Ositions' `so that when the valve 20' is `raise t by the pressure of the gas in the chamber.. 21,'it

nozzle 11, and three pipes 24, 25, and ,26,v Y

lead to vsaidvalve mechanism and communicate with the pipes 27, 28, and 29 in the nozzle 11, so that all three ofI these pipes discharge through the end of said nozzle. Steam is supplied to the pipe 24, and naphtha or any suitable hydro-carbon is suppliedv to the vpipe 25, while air is supe plied to the pipe 26; and the valve mecha.- nism is operated by the handle 30 to control the steam, and said mechanism is operated by the'handle 31 to control the air, while au adjustable indicator 32 is prolgnited and caused to explode,

. into t vided for tendering the ou, it being under-A stood that the valve mechanism is of anyand'the steamV pressure are controlled in any suitable or desired manner, so that the oil and 'steam or air, or the oil with both the steam and the air, are projected from the nozzle 11 against the valve 20, and the hydro-carbon vapor thus formed iills the mixing chamber 21 to form the gaseous mixture. The valve 20l opens under ressure,of.course, and allows a quantity o the mixture to escape through the nozzle 15 into the explosion chamber 9, and said valve in opening automatically opens the valve 18 and thereby admits air to the said explosion chamber 9, thereby forming a highly explosive mixture. It will be understood that after the burner is started the entire structure ,becomes highly heated so that the gases, under pressure,- enter the hot chamber 9, are immediately and the-force of their-explosion closes the valve 20 against the pressure of the supply of gas or vapor. Then, as soon 'as the ressure in the chamber 9 is reduced, the va ve 20 is again opened .by the` pressure in the chamber 21, and anotherexplosion is produced. .These explosions, it will be understood, follow each other'with such rapidity that the combustion of the gas or gaseous mixture is practicall continuous, thereby forming a flame of hig temperature which is blown from the funnel-shaped extension 10-directly into the water. This produces steam, of course, and the combustion of the gases produces products of combustion which add to the general pressure in the boiler.

A water pi e`33 is provided and arranged to connect with the pipe 34 which leads to the boiler. A ipe 35 connects with the pipe 34, between the boiler4 and the valve 36, which latter is in the main Water supply pipe. The pipe 35 is provided with a valve 37, and when the latter is opened, the contents of the boiler will be blown out through the ipes 34 and 35, in a manner that will be readily understood.

A. pressure gage 38 can be applied to the cham er 21 to indicate the pressurein this chamber, it being understood that this pres-` sure must always exceed the general boiler pressure, or otherwise the combustible mixture, formed by mixing the steam and air and hydro-carbon, could not force its way e 'explosion chamber 9, and no combustion Awouldl'jtake place. Of course, though, as previously stated, each explosion in the chamber 9 momentarily increases the kwhen they. to tlme,l it -cwill augment the pressure derived pressureiin this chamber to a point above the steam and air and oil supply, and it is this that is relied upon to close the valve 2O to prevent back pressure from escaping from the boiler. The different pressures,it will be understood, can beA regulated by the different valves to insure the desired results.

From the foregoing' it .will beV seen that the process involves the formation of a pri` marymixture, by the mixing of.`hydro.car-

bon vapcrwith steam or air,or with both,

in the chamber 21, and also involves the formation of a secondary mixturedn'- the explosion chamber 9, inasmuch as the combustible will depend upon the conditiensfand upon4 Vao mixture' discharged into the chamber 9 from the character of theilamedesireiand these'A thmgs are, or may be, regulated `from time be understood, in'orderA to obtain the desired results.

Thus the explosions in theexplosion A chamber 9""all't'e'rnate .with the intermittent preponderance of pressureV in the mixing or vaporizing chamber 21, as the pressure inV the latter must rise intermittently to a point above that of the main supply-of generated fluid pressure in the pressure chamber of the' boiler 1 previously described. Of course,I

when an explosion occurs in the chamber 9,' the pressure in the latter is momentarily greater than in the chamber 21, so that the valve 20 is closed, as explained, to prevent the back tire, so to speak, from reaching-the supply of mixture in the chamber 21, and to prevent premature ignition of said mixture.

What I claim as my invention is 1. The combination of a boiler for containing water to generate steam and means for causing combustion within the boiler so that the products of combustion serve to from vthe generation of steam,said means comprising an explosion chamber communicating with the interior of the boiler, a nozzle arranged to iis aV valve automatically opened by the pressure Yin the mixing chamber to admit ,the mixture ,to said nozzle. and means automatically controlled by said valve to admitV air to said explosion chamber, said valve being adapted to vbe automatically closed by the explosion prevent the back pressure from entering said mixing chamber.

2. In a pressure generator, the combination of a pressure chamber, an explosion chamber arranged to deliver fluid pressure sufficiently hlgh temperature by the com-` bustion therem to ignite the successive charges of mixture admitted thereto, instrumentalities for supplying fluids under pressure to said mixing chamber, and means automatically controlled b said controlling means to admit air to sai explosion chamber to dilute the mixture admitted thereto bysaid valve.

3. In a pressure generator, the combination of a pressure chamber, 'an explosion chamber arranged to deliver fluid pressure to said pressure chamber, a mixing chamber arranged to deliver a combustible mixture to said explosion chamber, controlling means whereby the mixture is intermittentlyi admitted .to said explosion chamber to cause successive explosions therein,` said explosion chamber being adaptedrto be, maintained .at

sufiiciently high temperature by the combustion therein to ignite the successive charges of mixture admitted thereto, and instrumentalities for supplying fluids under pressure to said mixing chamber, said explosion chamber comprising a nozzle extending into said pressure chamber, said mixing chamber having a second nozzle containing said controlling means and extending into said first nozzle, and said instrumentalities be comprising a third nozzle disposed in position to discharge into the second nozzle with a passage whereby the discharge from the third nozzle is turned back into said mixing chamber. v

4. The combination of a steam generating boiler, a mixing chamber for converting hydrocarbon fuel into a highly explosive gaseous mixture, avalve chamber provided with a valve adapted to permit passage of the mixture when a certain pressure is reached in said mixing chamber, an explosion chamber beyond said valve chamber and communicatinfr directly with the liquid in the boiler, and` means for admittin additional air to said explosion chamber, said valve acting automatically to intermittently admit4 charges of the mixture into said explosion chamber and to prevent back-fire from said explosion chamber to said mixing chamber.

- 5. The combination of a steam generating boiler, a fuel mixing chamber, an explosion chamber, a valve chamber intermediate said mixing and explosion chambers, and means for admitting air separately tothe explosion chamber, said valve chamber being rovided with a valve controlled by the relative pressures in the mixing chamber and the exploa sion chamber whereby an excess of pressure in the mixing chamber forces a charge into the explosion chamber and an excess of pressure in the explosion chamber closes said valve and the alternation of said excessive pressures rapidly opens and closes the valve to cause successive explosions from which the heat and products of combustion are directed into the boiler, the action of said valve serving to control the admission of the separate air supply tosaid explosion cham- ALEXANDER SEIDLER.
